Mellow the sharpness of rutabaga by simmering with white wine, broth, sauteed shallots, and fresh thyme. Finish with Parmesan for a welcome hit of umami.
Heat oil in a medium saucepan over medium. Add shallot and cook, stirring occasionally, until tender, about 5 minutes. Add wine and cook until reduced by half, about 2 minutes. Add rutabaga, stock, and thyme and bring to a simmer. Cook, covered, until rutabaga is tender, 20 to 25 minutes. Season with 1/4 teaspoon salt and pepper to taste. Sprinkle with cheese before serving.
